LG has already revealed the vertically curved Flex 2 at CES 2015 and now the company has showed off new prototype smartphone sporting a dual-edge display that is curved on two sides. 
Samsung had introduced the Galaxy Note Edge last year that has an edge which bends to one side. The LG’s dual edge display sports a 6-inch HD Active Bending P-AMOLED display that bends at both edges, giving you the ability to swipe and tap through. Users also get a side-view of the display that is 0.7 mm thick at both the right and left edges. However, the resolution on the LG dual edge device is only 1280 x 720 while the Samsung Galaxy Note Edge has Quad HD 2560 x 1440 display in addition to the 160 pixels for the curved edge on the right side. The dual edge display technically adds two additional screens on the phone.
It must be noted that the smartphone at present has no name and is merely a prototype. But, LG might soon give more details about the device. source 1| via
